Oh definitely. As long as the heat isn't too much, they can go up to 2000 or more especially if your pumping that much CO2. Check the ppfd on a bright sunny day and you'll understand what I'm talking about...
I'm curious about your EC and what medium you're using?
With some strains you may get bleaching of the flowers having too high of ppfd. Perhaps it would take more than 1200 though but something to watch for.
